Answer:
a) we know that resistance is directly proportional to the length of the conductor as length increases the resistance also increases so to direct the current with least resistance, then the direction is perpendicular to side B only other sides have a larger length than B.
b) = 4.35 × 10⁻⁴ m/s
time = 229.56 s
Explanation:
Given:
a) we know that resistance is directly proportional to the length of the conductor as length increases the resistance also increases so to direct the current with least resistance, then the direction is perpendicular to side B only other sides have a larger length than B.
Dimension = 0.2m × 0.1m × 0.02m
ρ = 1.69×10⁻⁸ Ωm
= 8.49 × 10²⁸ e−/m³
Potential difference across the solid = 0.001 V
Now,
from Ohm's law V = I × R
here
V is potential difference
I is the current
R is the resistance
or
R =
also,
R =
Here, l is the length
A is the area
and,
the drift speed, =
substituting value of I in the above equation, we get
=
on substituting the values, we get
or
= 4.35 × 10⁻⁴ m/s
also,
the time taken, t =
=
= 229.56 s
Answer: Universe.
Explanation: In addition to the solar system, the heliocentric model stated that the sun was the center of the UNIVERSE.
Every plant orbits around the sun, which makes our universe whole and bright.
Hope this helps you out! ☺

A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies
